果真在巴西印第安Botocudo古DNA中发现了波利尼西亚成分

Identification of Polynesian mtDNA haplogroups in remains of Botocudo Amerindians from Brazil
The identification of these two Polynesian haplogroups was confirmed in independent replications in Brazil and Denmark, ensuring reliability of the data. Parallel analysis of 12 other Botocudo individuals yielded only the well-known Amerindian mtDNA haplogroup C1.

的确是B4a1a1a,波利尼西亚标记。

以往疑似B4a1a1。

A possible exception was the  finding of the motif seen in the HVSI of Polynesians (16189C,16217C, 16247G, 16261T) in two individuals from a Peruvian archeological site from the 14th and 15th centuries (52). However,
the coding mutation 14022G that is critical for definition of the Polynesian motif was not investigated in these remains.


马达加斯加关联:

It has been estimated that between 1817 and 1843 ~120,000 slaves were brought from that region to Brazil (53), some of them probably going to Minas Gerais, Espirito Santo, and Bahia, to work close to areas occupied
by Botocudos.
